From b06689cc1b0446b959ed1a41b4f8dd892aa6b331 Mon Sep 17 00:00:00 2001 From: Amit Cohen Date: Tue, 23 Jul 2019 10:57:41 +0300 Subject: [PATCH] mlxsw: spectrum: Expose KVD size for Spectrum-2 Unlike Spectrum-1, the KVD (Key-value database) of Spectrum-2 is not partitioned, so only expose the entire KVD size. This enables users to query the total size of the KVD. Signed-off-by: Amit Cohen Acked-by: Jiri Pirko Signed-off-by: Ido Schimmel Signed-off-by: David S.
